Star Trek: Deep Space Nine

Episode: DS9 465 - Improbable Cause

Mila, a Cardassian woman, served Enabran Tain for over three decades as his housekeeper. She also believed in Garak, and his loyalty to both Cardassia and Tain.

In 2371, Tain considered to have Mila killed because she knew too much. However, Mila survived, only to be slain by Cardassian-Dominion forces while protecting Garak from them.
